Abstract:: Incubation experiments with an acid poorly drained soil have shown that the application of neutral soluble salts influenced the level of extractable Mn. The application of a salt which lowered the soil pH either increased the extractable Mn or retarded the oxidation and/or fixation of extractable Mn. This effect was...

Creator:: Hile, Mahlon Malcolm Schallig
Abstract:: Experiments were conducted to determine the effect of environment and several plant growth regulators on the physiology, quality, and agronomic performance of snap beans (Phaseolus vulgaris L. ) and spring wheat (Triticum aestivum L. ). The potassium salts of naphthenic acid and cyclohexanecarboxylic acid, received particular attention. Application of potassium...

Creator:: Jarrell, Wesley M.
Abstract:: Field studies designed to study residual effects from fertilizer molybdenum were initiated in September 1971 on established grass-clover pastures at ten sites in Western Oregon. Treatments were 0.0 and 1.12 kg molybdenum /ha on plots receiving 0-35-0-20S fertilizer (elemental sulfur-S) and 0.0, 0.56, 1.12 and 2.24 kg molybdenum /ha on...

Creator:: Cooper, Clee Scott
Abstract:: Field, greenhouse, growth chamber and laboratory experiments evaluated factors affecting establishment, survival and production of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.) Field studies investigated the effects of a barley companion crop, seedling year harvest management and nitrogen and phosphorus fertilization upon stands, survival and subsequent production...

Creator:: Kerridge, Peter Campbell
Abstract:: Wheat varieties of differential tolerance to Al were used in a series of nutrient solution experiments to study the inhibitory effects of Al on growth and nutrient uptake. The pH and the Al and P concentrations were rigorously maintained to prevent the confounding effects of Al and P precipitation and...

Creator:: Kauffman, Marvin Dean
Abstract:: The application of lime to an acid Nekia soil significantly increased the yield of winter wheat and alfalfa in a field experiment. Crop yields maximized when the lime was partially mixed into the surface four inches of the soil. Thorough mixing of the lime into the surface six inches of...
